Introduction to Stryker.NET
Stryker.NET is an advanced tool designed for mutation testing in .NET Core and .NET Framework projects. Mutation testing offers a unique way to test the effectiveness of your unit tests by intentionally introducing bugs or "mutants" into the source code to check whether the tests can catch the errors. This approach helps ensure that your tests are robust and can adequately handle unexpected changes in code.
If you're new to mutation testing, or want to explore what Stryker.NET can do, you can find more detailed information at stryker-mutator.io. The Stryker family also offers mutation testing tools for other programming languages, such as JavaScript, TypeScript, and Scala.
